Image Steganography is the method of hiding the presence of data in cover images .Here we propose the revised version of Roshan Shetty B R et al. whose work was inspired by C. Chang et al.In earlier work only the RED & GREEN components of cover image pixel was used and reference matrix used was of order 27 x 27 and embedding capacity was 3 bits per pixel.In this paper we use RED, GREEN & BLUE components of cover image pixel and reference matrix of order 9 x 9. Hence, the embedding capacity is 4.5 bits per pixel.Prior to embedding the data we use compression and encryption so that more and various digital media are securely embedded in cover image.
